The invention discloses a vehicle side wall rear connecting structure and an automobile. The vehicle side wall rear connecting structure comprises a C column inner plate, a wheel cover inner plate, a C ring connecting piece, a roof side rail inner plate, a rear reinforcing plate and a D column. The C-ring connecting piece is fixedly connected with the upper edge beam inner plate, the C-column inner plate and the wheel cover inner plate, and a C-ring cavity is defined by the C-ring connecting piece, the C-column inner plate and the wheel cover inner plate. The D column is fixedly connected with the rear reinforcing plate, the C column inner plate and the wheel cover inner plate, and the D column and the C column inner plate define a D-ring cavity. The roof side rail inner plate is fixedly connected with the rear reinforcing plate, and the wheel cover inner plate, the roof side rail inner plate and the rear reinforcing plate are fixedly connected with the C column inner plate; and the outer wall of the C-ring cavity, the outer wall of the D-ring cavity, the roof side rail inner plate, the rear reinforcing plate and the wheel cover inner plate are enclosed to form an annular reinforcing part. The rear structure of the side wall presents integrity and coherence, so that the torsional rigidity, the torsional mode and the NTF performance of a vehicle body are improved.
